- I did a physics lab and got some values. I want to check them theoretically to see how the results differ. From this diagram, answer the following questions: The laws to be verified included the conservation of current in a node, the addition of potentials for components in series, and the addition of currents for components in parallel. NOter that the second battery was connected in the opposite direction to the current, this is the aim of the question. The data : R1: 1094 ohm R2 : 998 ohm R3: 1094 ohmR4: 25 ohm Source 1 : 5 V SOurce 2 : 1,5 VCurrent=1A V_ab=-12V V_bc=21V 4d. What is the total rate at which electrical energy is dissipatate in R1, R2, and R3 resistors. 4e. What is the power outpur of the 26V battery? 4f. At what rate is the electrical energt being converted to other forms in the 10V battery? 4g. Show that power output of the 26V battery equals the overall rate of dissipation of electrical energy in the rest of the circuit?The diagram below shows the experimental set-up for observing thephotoelectric effect. The table provides values for the work function for several elements. (The work function is the amount of energy required to free the outermost electron from that element.) It is found that a certain voltage stops the current from flowing around the circuit. When the experiment is repeated, it is found that the stopping voltage has increased. Which of the following could explain the change between experiments? a) The metal was changed to one with a lower work function. b) The light intensity decreased. c) The light frequency decreased. d) None of the above.

- In problem 13, solve for the Hall voltage (in microVolts) that would be generated if 8.1 Amperes of current are used to probe the material. 5 sig figsPlease fill out the template below with the work for this problem. Note that you need to have a picture, a list of knowns and unknowns, the general equation/s you will use, and the math steps to solve for the unknown, only plug in the numbers after you have solved for the unknown, and the answer with units included. Question 1: A current of 2.72 A flows through a wire. How many electrons flow past a particular point in the wire every 15 seconds?The equation for the graph is y= x^2 Resistance = (Voltage/Current), however I don't think that would work in this case as it is not a linear graph. It might have something to do with the equation but i'm not sure Don't use chat gpt It Chatgpt means downvote
